[CentOS] /mnt/sysimage/dev folder in rescue mode

If I boot C5 from DVD in rescue mode,
chroot to /mnt/sysimage, and try to do a
grub-install /dev/sda it will fail because
the /dev folder is empty (in the chroot environment).

Until now I've then created the missing nodes manually,
but is there a smarter way of doing this? Some devfs
that needs to be mounted on top of /dev?
